Semiconductor light emitting device with protrusions to improve external efficiency and crystal growth |
| 摘要 |
A substrate has at least one recess and/or protrusion formed in and/or on a surface thereof so as to scatter or diffract light generated in an active layer. The recess and/or protrusion is formed in such a shape that can reduce crystalline defects in semiconductor layers.
